SUBJ: SWS AURORA WATCH
ISSUED AT 2357 UT ON 01 Nov 2018 by Space Weather Services
FROM THE AUSTRALIAN SPACE FORECAST CENTRE

Geomagnetic activity is expected to reach active to minor storm levels
on UT day 03 November and active levels on 04 November. The
disturbance is due to the expected arrival of CIR and HSS associated
with a large recurrent equatorial coronal hole. The approaching
coronal hole has produced solar winds reaching 650 km/s at the
location of STEREO-A. Similar effects are expected at Earth. The
aurora may be visible on the local nights of the
UT day 03-04 November from Tasmania and coastline of Victoria. Aurora
alerts will follow if significant geomagnetic activity actually
occurs.
